Police said that on Feb. 5, the two, described as males in their late teens, held up a Citgo gas station at 900 34th St. N.

Since then, there have been three more convenience store robberies.

The latest was late Wednesday morning, just hours after police put out a news release about the other incidents. Just after 11 a.m., police got a call from a Sunoco gas station at 6800 Fourth St. N. Officers said two men entered the store and robbed a clerk and delivery driver.

In the first holdup, at the Kenwood store last week, a teen armed with a handgun reached over the counter and threatened the clerk, police said. The second teen walked around the counter and took cash, loose change and lottery tickets.

Then, at about 9:50 p.m. Monday, two men went to a Chevron gas station at 5405 Dr. Martin Luther King St. N, pointed a gun at the clerk and took cash from the register. They also took the store employee's cellphone.

Police said the robbers did the same thing 15 minutes later at the KR Food Store at 2835 16th St. N.

Video footage from the first robbery shows that one of the suspects was wearing a dark, hooded sweatshirt with the words "Pinellas Park" on the front.

Anyone with information about the incidents is asked to call Detective Wallace Pavelski at (727) 893-4823 or the tip line at (727) 892-5000.
